Local seismic arrays were deployed at two locations along the San Andreas fault (SAF) near Parkfield, California, before and after the 2004 M 6.0 Parkfield earthquake. Using local earthquakes we determine the anisotropic field within 1– 2 km of the main trace of the SAF at the two array locations separated by 12 km. The initial array, near the SAFOD site, was deployed for six weeks in October a...

Understanding the impact of fault zones on reservoir trap properties is a major challenge for variety geological resources applications. Fault in cohesive rocks are complex structures, composed 3 components: rock matrix, damage zone fractures and core rock. Despite diversity methods to estimate permeability/drain properties, up date none them integrate simultaneously all three components, nor t...

The hypercube has been one of the most popular interconnection networks for parallel computer/communication system. In this papers, we assume that each node is incident with at least two fault-free links. Under this assumption, we show that every fault-free edge lies on a fault-free cycle of every even length from 6 to 2 inclusive even if it has up to 2n − 5 link faults. The result is optimal w...
